Yes the ones with the winter package did have the lsd, but even the 525i with either a m20 or a m50 would handle a lot better with and lsd in the snow . I had 2 e28 528e (both slower and less hp then the e34 525i) one had an open diff and it sucked in the snow and was always getting stuck in the snow. The one with the lsd was a beast in the snow. I drove in a blizzard where we got 16inches of snow and never got stuck. At one point I could feel the car pushing through the snow and I had it floored just to keep it moving. I felt like I was driving a boat, but I never got stuck. I currently have a e34 535i with an open diff, I do not like it in the snow. I got a 3.46 lsd that I am rebuilding that will be going into the car at some point in time. I hope that this will be a game changer like it was in the e28.
